Asus EAH4830 Crossfire problem

[Elijah]

Have problem with getting Crossfire to work for my two Asus EAH4830 card. Is reasonably new when it comes to cross four and appreciate all the help. The cards are in an Asus P5Q Pro card that will support cross fire.

In the Catalyst control center I see both cards, but the secondary is that disable. Crossfire menu says that the Crossfire bridge connection is not connected properly.

Read somewhere that one had to update the BIOS so that the motherboard should have software support for this cross fire. BIOS version 1406, but my BIOS running on the latest, 1501, and it will not update to an old version of the BIOS.

Is there someone who has seen this before or who may have tips to the solution?

Have seen that some cross system has four physical adapters connected with a cable, but the following is not considered when I bought the cards. Is this the cable I am missing or will the motherboard take this automatically?

The cable must be yes ...
Ebay sells it in the numbers and hope it will follow with video cards.
Some manufacturers are relax on it.

Otherwise, it is very difficult to find it. And even if it is similar to a cable that Nvidia SLI uses so you can not use this, Nvidia has much lighter touch and will not fit on the ATi card.

As MindSpace says you must have crossfire bridge completely to, but works fine with one, if you call or e-mail support department where you bought the cards they send you is sure to have a couple, sitting with a cabinet

BIOS, you do not update to bring CrossFire, it works fine on the P5Q Pro, but you need to put a crossfire bridge or two.

Is this internal cables to connect between cards? Or is it the external cables to connect the DVI to DVI?

[samar69]

They are located between the internal cards - on top of the cards.
